processing unit (CPU), the memory, and the input/output devices (I/O) are the main three building blocks of the Von Neumann computer systems connected using the system bus. The components of the model are composed of memory, arithmetic logic unit (ALU), input/output, and the control unit. The memory is where all the data information is stored, in present computers it is call the RAM. The ALU is where the calculation and processing of information take place. The input gets information into the computer like

implement various operations on files. 15.1 Introduction Most programs written in C++ handle large volumes of data that needs to be stored permanently on secondary storage devices such as hard disk. The data resides in these devices in the structure of files. A file is basically a collection of bytes stored on a secondary storage device, such as disk. Programs are

memory is enable a computers to store, at least temporarily, data and programs. Mass storage device is allows a computer to permanently retain large amounts of data. Common mass storage devices include dish drives and tape drives. Input device is usually a keyboard and mouse, the input device is the conduit through which data instruction enter computer. Output device is a display screen, printer other device that you see the computer has accomplished. Central processing unit (CPU) is the heart of the

in "ladder logic", which strongly resembles a schematic diagram of relay logic. The main difference from other computers is that PLCs are armored for severe conditions (such as dust, moisture, heat, cold etc) and have the facility for extensive input/output (I/O) arrangements. PLC applications are typically highly customized systems so the cost of a packaged PLC is low compared to the cost of a specific custom-built controller design. On the other hand, in case of mass-produced goods, customized control

word 'compute', which means to calculate. A computer is an electronic machine, devised for performing calculations and controlling operations that can be expressed either in logical or numerical terms. In simple words, a computer is an electronic device that performs mathematical and non-mathematical operations with the help of instructions to process the data to achieve desired results. Although the application domain of a computer depends totally on human creativity and imagination, it covers a

best input and output methods for various hardware and software. Accuracy of Data Accuracy of data input is important. What method of data input would be best for each of the following situations and why: As far for printed questionnaires the best method for data input would be a keyboard, because it permits one to produce the required test that formulates the questionnaires. The best method for a telephone survey would be voice recognition and recording system because a voice input device

Neumann and his collegues introduced an architecture that was created to where computers can perform and execute many different types of tasks at the same time. Von Neumann's architecture is divided into different parts. The input device, output device, auxiliary storage device, main memory and the central processing unit. (CPU) which includes the control unit, arithmetic logic unit and the registers. Today most computers are still based off of Von Neumann's architecture and are also known as Von Neumann
